I'm using a PC with two Intel Gigabit adapters (i8254x). When Linux
(RedHat 7.2, kernel 2.4.24) boots, it calls "insmod e1000.o" and the
driver initializes and takes control of both adapters. Is there a way to
restrict the e1000 driver to only one adapter? I've searched in the
driver parameters but there is nothing obvious.

For what purpose is this needed ?

The following doesn't quite answer your question, but it
may help.

I'm running FC6. The driver module loaded for each of my
ethernet interfaces is controlled by entries in
/etc/modprobe.conf
for example:
alias eth0 3c59x
alias eth1 e100

This does not work. Don't use it. This is a misuse of the module aliases because it does not mean that the actual interface names match the alias names.

I think RH 7.2 has a similar file, but I believe that the
file was /etc/modules.conf. Try
man modules.conf
You may be able to set them to use different drivers, or
even set one to have no driver:
alias eth0 e1000
alias eth1 off

I never used RH 7.2 and I'm not sure this would work.

I do not need to use RH to know it does not work.
When eth0 is invoked, the e1000 module is loaded, takes control of both adapters and creates eth0 and eth1.
